PATENT WALTER ROBERT KROPF, OF SAN FRANCISCO, CALIFORNIA,

ASSIGNOR OF ONE-HALF CORNER BRACE.

Application filed May 31, 1921.

To (2112 whom it may concern Be it known that I, WALTER ROBERT Knorr, a citizen of the United States, and resident of San Francisco, county of San Francisco, and State of California, have invented a new and useful Corner Brace, of which. the following is a specification.

. The present invention relates to corner braces which, while capable of general application to wood and the like structures, has particular reference to furniture braces.

As heretofore practiced especially in the assembling of box couches and other like furniture pieces the corners are not only braced but the means used for bracing usually acts also as a means for attaching or joining the feet or corner post to the frame members. These bracing devices should be more or less readily attachable due to the fact that the furniture pieces are crated and shipped with the feet or corner posts unattached with the same set up either just before the article has been sold or afterwards. In the most conventional types of these braces practically no successful attempts have been made to produce a combined brace and attaching device for the feet or corner posts which will not become loose yet exceedingly simple in construction, easily applied and capable of being turned out in large numbers at an unusually modest cost. The present invention contemplates removing all objections to these heretofore known types of braces and to provide a practical solution for the many problems involved connected with the same.

The illustrations in the accompanying drawing have been selected for the express purpose of identifying more clearly the outstanding features of the device and Figure 1 thereof is a plan view of the cut blank from which the device is made; Figure 2 is a perspective view of the device as stamped from the cut blank shown in Figure 1; Figure 3 is a sectional view on the line III-III Figure 1 and Figure l is a perspective view illustrating the application of the device.

Referring to the drawing in detail, for the sake of economy and convenience it is preferred to produce the device from a sheet of relatively stiff metal, the sheet being first cut or stamped out leaving the fiat cut blank shown in Figure 1. This cut blank is then stamped, bent or otherwise treated to produce the complete device shown in Figure 2.

the spurs 6 in one Patented July ill, 19.22. Serial No. 473,986.

At the time of cutting or stamping the blank shown in Figure l the nail or screw holes 5 may be made, as well as the spurs 6. The cuts 7 shown in full lines in Figure 1 may be also produced at the same time the outline is made. The dotted lines 8 in Figure 1 represent the bends to be subsequently made.

The method producing the device is immaterial in so far as concerns the use of the same; however, the above description will help to bring out the salient features. Considering the device in its completed form and as shown in Figures 2 and 4 a tongue A having prongs B on its front edge and or both of its sides is made to be driven into the corner post C from the apex of one of its edges with the bent angle strap D fixed to the frame member E and with the angle web F fixed to the opposite frame member G. The straight bottom strip H extends between the two frame members E and G and with its respective ends fixed to the lower edges of the same.

The angle strap D and the angle web F are of the same length and their bent ends are likewise of the same length and angularity. The bottom strip H is slightly longer than the combined lengths of the angle strap and the tongue. It is also to be noted that the angle web F is part of the bottom strip H for a portion of the latters length.

The angle strap D, the angle the bottom strip H rigidly bind not only the two frame members E and G together but they also act to clamp the same to the sides of the corner post C with the tongue A holding the corner post in the V of the corner made by the ends of the frame members and resisting any tendency of the post to become wobbly or even loose. The spurs 6 will be firmly embedded in the corner post and the prongs B will project through the post and engage the side of the frame member G or E as the case may be,

As will be seen, the device, while very simple, provides many different angular tie pieces which may be relied upon to hold the corner post or feet in position and brace the entire structure.

I claim:

1. As a new article of manufacture, a corner brace for furniture produced from a sheet metal blank and including a tongue web F and made to be embedded in the post of a corner joint, a strap formed integral with the tongue and extending transversely thereof adapted to be fixed to one frame member of the wood structure, a web member also formed integral with the tongue and extending transversely thereof oppositely of the said strap adapted to be fixed to a second frame member of the wood structure, and a strip formed integral with the web member and with its respective ends adapted to be rfixed to each of the said frame members of the wood structure. 2. A corner brace for furniture produced from a metal sheet cut long tudinally and bent both longitudinally and transversely to form a tongue, and transverse bracing strips,

7 two of the strips extending in opposite direcnamed strips, said tongue member having prongs on its forward edge and spurs struck up from its sides and adapted to be embedded in a corner post of a furniture structure, said two first-named strips having their respective ends bent outwardly and adapted to be attached to frame members of the furniture structure.

3. A corner brace for furniture produced from a. metal sheet cut longitudinally and bent both longitudinally and transversely to form a tongue, and transverse bracing strips, two of the strips extending in opposite directions from one another at right angles to the tongue and with their fiat surfaces in the same vertical plane, a third strip extending lengthwise of the two first named strips and with its flat surface in a plane intersecting the plane of the said two first-named strips, said tongue member having prongs on its forward edge and spurs struck up from its sides and adapted to be embedded in a corner post of a furniture structure,

said two first-named strips having their respective ends bent outwardly and adapted to be attached to frame members of the furniture, and the ends of said third-named strip adapted to be also fixed to said frame members.
